Zymogen granules in enzyme liberation and activation in pea seeds.
Pea seeds have zymogen-like granules that contain an inactive form of the enzyme amylopectin-1,6-glucosidase. The enzyme can be liberated from the particles in the inactive form and can then be activated by limited proteolysis with trypsin.
